▎ 摘  要

NOVELTY - Composition comprises a metal oxide, distilled water or organic solvent, oxidation-reduction indicator, and a metal oxide. USE - Composition for detecting and blocking ultraviolet rays in display unit (claimed). ADVANTAGE - The composition detects and blocks ultraviolet rays that affects the chromatophore including the collagen of skin. The skin aging and melanin pigmentation including the fine wrinkle and elasticity degradation is prevented. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for detecting and blocking ultraviolet rays, which involves: (A) adding a redox indicator to distilled water or an organic solvent to prepare a mixture; (B) adding a metal oxide to the mixture to prepare a composition; and (C) observing a change in color when the composition is irradiated with ultraviolet light.
